ROLLER-SKATE;

Specification of Letters Patent.

Patented Mar. 2, 1920.

Application filed may, 1919. Serial No. 300,528.

To all whom it may concern Be it known that I, JOSEPH WISNIEWSKI, a citizen of Poland, residing at New Acme,

inthe county of Sheridan and State of Wyoming, have invented certain new and. useful Improvements in Roller-Skates, which the following is a specification.

This invention relates to roller skates, and more particularly to skates for use on tracks.

The object of the invention is to provide a simple, strong and cheap skate of this character, for use by rai road men and others.

Another object is to so construct a roller for a skate of this character that there will be a minimum amount of friction between it and the rail over which it passes to enable the skater to obtain maximum speed.

With the foregoing and other objects in View, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the preciseembodiment of the inventlon herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings Figure l is a side elevation of this improved skate shown applied,

Fig. 2 is an enlarged detail perspective view of the skate, and

Fig. 3 is a transverse vertical central section thereof.

In the embodiment illustrated, the skate 1 constituting this invention is shown in the form of a body member or frame here shown rectangular, although obviously the contour thereof may be varied when found desirable. This body member comprises side bars 2 connected by cross bars 3 at the ends and intermediately the length thereof. These side bars 2 have longitudinally disposed spaced slots 4 for the reception of attaching straps 5 for connecting the skate to the foot of the wearer as shown in Fig. 1.

Hangers 6 are secured to the side bars 2 midway the length thereof and depend therefrom, said hangers being here shown in the form of triangular plates in the tapered ends of which is supported a shaft 7. This shaft 7 is threaded at its opposite ends and projects beyond the outer faces of the hangers and held in operative position by stradd e a rail R and extend downwardly nuts 8 and 9 disposed on opposite faces of the ban ers.

A bal bearing roller 10 is mounted on theshaft 7 between the nuts 9 and is provided at its opposite ends with radially extendm flanges 11 which are designed .to

on opposite faces thereof a considerable distance to hold. the roller against lateral movement, and to avoid danger of its slipping off the rail. A rail tread engaging element 12 is disposed midway between the flanges, 11 on the periphery of the roller as is shown clearly in Fig. 3, said element being comparatively narrow so as to provide a proper support for the skate and yet have a minimum amount .of frictional contact with the'raiI to provide for a maximum speed.

Upstanding arcuate clips 13 are arranged at the rear corners of the body member of the skate, and are designed to engage the heel of the shoe of the wearer to assist in retaining the skate in operative position on the foot.

Depending from the four corners of the frame of the skate are braking elements 14c to assist in stopping when desired.

A pole P of bamboo or other light material is intended to be used in connection with these skates to enable the user to retain his balance on the rail and to use it as a pusher when found desirable, and also to assist him in coming to a stop.

From the above description it will be obvious that a skate of the character described will enable the user to cover a maximum mileage with the exertion of a minimum effort, owing to the slight amount of friction between the skate and the rail R in connection with which it is to be used.

From the foregoing description, taken in connection with the accompanying drawings, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention appertains and while I have described the principle of operation of the invention together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and that such changes may be made as are within the scope of the claimed invention.

Having thus fully described my invention, what I claim as new and desireto seflanges extending radially beyond the pe- 10 cure by Letters Patent, is rimeter of the roller.
